I like to distinguish the science in science fiction into several catagories.
Impossible Can't happen, get over it or you are writing fantasy.
Not proven. Might be possible, or not. We don't know. (use sparingly in "Hard SF")
Theoretically Possible but we don't know how to do the engineering.
Enginering difficult We know one way to do it, but it is too expensive or difficult.
Most of the high tech in Traveller counts as theoretically possible.
You frame the situation very well, Bob. To add my own two cents, I'd like to quote my wife -- a woman trained as both an Applied Mathematician and a Quantum Theorist. With a smile she likes to say, "All science-fiction is bullsh!t"
Now, she likes SF a lot (the more science-based the SF the better, given her education); the point of her statement is this ...
Seen from a mathematics point of view, physics is a sequence of interlocking "things which are mathematically true, and which can be demonstrated as such". There are parts we don't understand yet -- parts we don't understand how or where they fit into the mathematical expression of the reality of the universe -- but that doesn't mean they are "beyond science". They're just beyond science at this time, pending further testing and investigation.
My wife's point in calling all SF bullsh!t is that, in practice, physics is a whole expression of how the universe works. When TML-type flamer folk screech about the plausibilty of harder or softer SF principles (not dinging you here Bob, you're talking reasonably) they miss one crucial point: as soon as you violate one principle of science for your SF, you've violated them all, by extension. Physics has to "hang together" mathematically to be a proper expression of reality.
So, people who scorn those who accept "blaster pistols" in their SF while themselves countenancing FTL drive are hypocrites, at the very least. Yes the "hard SF" bullies tend to favour science-fiction principles which grow more directly out of our current math and physics theory, but they also ignore the fact that they are still entering the realm of science-FICTION; they are still leaping from a real scientific principle to an as-yet unreal or unproven extrapolation.
As my wife says in corollory to "All science-fiction is bullsh!t" ... "if an SF principle were scientifically true, then it would already be [at least mathematically] real and not fiction"
There's a British saying, "In for a penny, in for a pound". Once you're into the realm of fiction, you're there. How deeply your fiction contravenes reality is irrelevant from a scientific perspective, because scientific, mathematical reality is not a question of degree. Something's true or it's not true.
I'm not the scientist in this family, so any errors in expressing these ideas are entirely my own. If anyone has any legitimate questions, I will try to pass them on to my wife. I will not, however, answer anything even vaguely flame-like or sneering.
Oh yeah ... the "what about Einstein?" question. Einstein didn't re-create physics, he simply noticed a very small aspect of physics which didn't work as it was supposed to work. In investigating this anomaly, Einstein eventually discovered that whole sections of how we previously understood physics were, in fact, in error. To put it in gamer terms: Einstein didn't intend to write a new rules system, he meant to fix a broken rule or two, and in doing so, he discovered some major flaws in the existing system which needed to be corrected and explained.
Time to shut up now, I think. Thanks Bob for bringing up the topic of plausibility and SF. You are right that there are levels to which an SF story can use science. All I'm saying is that all SF is fiction first and foremost, no matter how much science it incorporates.
